         9 . The medical device system of  claim 1 , wherein the second adhesive is a silicone-based adhesive. 
     
     
         10 . The medical device system of  claim 1 , wherein the first adhesive is an acrylate adhesive. 
     
     
         11 . The medical device system of  claim 10 , wherein the second adhesive is an acrylate-based adhesive having a lower acrylate concentration than the first adhesive. 
     
     
         12 . The medical device system of  claim 1 , wherein the second substrate has a surface area greater than a surface area of the first substrate. 
     
     
         13 . (canceled) 
     
     
         14 . The medical device system of  claim 1 , wherein the first side of the second substrate comprises a first portion comprising the second adhesive and a second portion absent of the second adhesive, and wherein the second portion extends up to an edge of the second substrate for providing an air channel between the second substrate and the patient's skin. 
     
     
         15 . The medical device system of  claim 1 , wherein the second substrate comprises a cut-out extending from an edge of the second substrate towards a centre of the second substrate so as to provide an air channel between the second substrate and the patient's skin. 
     
     
         16 . The medical device system of  claim 1 , wherein the second substrate comprises one or more breathability holes for providing an air gap between the first substrate and the patient's skin.
